Evidence Gap Map

Welcome to version 3.0 of the Digital Finance Evidence Gap Map (EGM)

This interactive EGM matrix of 14 digital finance product categories, 32 design and delivery categories and 10 outcome categories contains 75 impact studies. A supporting methodology document is also available.

How to use the EGM

There are two views of the EGM. The first view, Digital Finance Studies, shows the total number of studies that were conducted on a particular product, plotted against the client outcomes which were tested. The objective of this view is to give the user an overview of the impact literature on digital finance and highlight which digital finance products were examined, against what outcomes and how frequently.

The second view, Digital Finance Results, presents the results of each test that was conducted on a particular client outcome. The colour codes circle show the level of impact (green is positive, red is negative and orange is no impact) and the number within the circle shows the number of tests on the client outcomes. Most studies tested more than one outcome, and many studies tested more than one variation on that outcome. For example, a study that tested the outcome clients improve savings behaviour, may have provided results on 1) the change in frequency of saving and 2) the total value of savings. Thus, the number of tests in the results view, may not equal the number of studies.

In both views, you can filter by different variables to gain a more precise picture of the impact of digital finance on various client outcomes—you can click on any circle to access further information on the studies.


The EGM was last updated in October 2019.

We are tracking several impact studies that are in progress and impact studies that were released after the literature review ended in early August 2019. These will be folded into the next version of the EGM.
